RATCI-IET HANDLE.

Original application filed December 26, 1918, Serial No. 268,347'.

Getober 23, 1919.

To all whom t may concern.'

Be it known that l, MALCOLM D. BIKER, a citizen of the United States, and a resident of Dover, Morris County, and State of New Jersey, have invented certain new and useful Improvements in Ratchet Handles, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My present invention relates to lifting jacks and particularly to the handle mechanism for operating the same.

The objects of the invention are to provide a simple, strong and easily assembled ratchet handle construction which may be operated in either direction and which further may be operated with or without a lever.

l Briefly the invention resides in a construction embodying a ratchet member which is suitably keyed to the spindle to be operated and a housing journaled on hub portions of the ratchet member and provided with a reversible pawl for engaging the ratchet, said housing being preferably provided with a handle for manual operation of the same and a socketyfor the reception of an operating lever and being further constructed with a side which is opened up for the reception of the ratchet and which is subsequently closed down over the ratchet to secure the parts in assembled relation.

Other features of the invention and details of construction will appear as the speciiication proceeds.

In the accompanying drawing I have illustrated the invention embodied in one of its simple, practical forms, but would have 'it understood that modifications in structure may be made without departure from the true spirit and scope of the invention as defined in the appended claims.

In said drawing:

Figure 2 is a horizontal sectional view, taken substantially on the plane of line 2-2 of Figure 1.

mechanism, taken substantially on the plane of line 4 4 of Figure 3 and illustrating particularly the manner in which the parts are assembled.

The jack construction illustrated is of my own invention and is disclosed and claimed in my co-pending application, Ser. No. 268,347, the present application being a division from that case.

Briefly this jack construction consists of an inner post member 10 having a suitable base 11 and provided above said base with a cylindrical outer surface 12. Mounted in the upper end of this post is the nut 13, the same being held against rotation, as by means of keys 14. Also carried by this post at the upper end is a stop collar 15, having an outer cylindrical surface 16 of somewhat larger diameter than the cylindrical surface 12 of the post and provided with a lower beveled end 17.

20 designates the lifting screw which lits the nut and is provided with an upper cylindrical extension 21. as operated by a worm gear 23, connected with the screw by keys 24, said gear supporting an anti-friction thrust bearing 25, which provides a thrust connection between the gear and the lifting head.

30 designates an outer shell or sleeve which is turned at its lower end at 31 to slidingly fit the cylindrical portion of the post and which has a slightly larger cylindrical portion 32 in sliding engagement This screw is shown with the collar surface 16. A beveled shoulder 83 between the surfaces 31 and 32 cooperates with the beveled stop shoulder 17 to limit the upward movement of the sleeve.v

The upper end of the sleeve member carries a lifting head 34 provided on the under side with a cylindrical pocket for the extension 21 and this head is also formed with a housing 35 in which is journaled the worm 36 in position to operatively engage."y

bered 'to receive the.V ratchetand ,provided y with lugs=g43fto space the toothedportion ofthe ratchet from the inner surface of said chamber. This housingis preferably provided With a socket 44 VJfor the reception of an actuating lever, and also With a handle 45 by Which it can be easily operatedby hand. The housing is also formed with a radial j pocket;y 46 for a spring pressed 'i paWl 47.

The housing casting is made with an integral.: iconen portion-,48; yhaving.an Aopening g forthe receptionorl the bearinghub di or theoratchet. This cove1.\vhen raised, as shown in Figure 4l, permits the insertiongol` the.,-pavl ,4r/.land the( ratchet 38.5into their respect/ivm seats y' in thephousing andafter such "=,partsaref'inposition the cover is bent downv against-f the;l spacingglugsl), i atten which the lugs 50 are bent.downover@the edge! othe side Wall,A asshoivnaini Figure? 2y to; loclL-,the sameninclosedz position.
